Use natural sort instead of lexicographical sort for decks

Lexicographical sort doesn’t sort nicely for titles with numbers in them, e.g. “My Deck v10” will be sorted before “My Deck v9”. Natural sort (https://en.wikipedia.org/wiki/Natural_sort_order) gives a better sorted output and is used in many places like windows file explorer.
